Health Literacy and Internet- and Mobile App-based Health Services: A Systematic Review of the Literature.

As information and communication technologies (ICTs) are increasingly used to support and deliver health care, access to Internet-based health services is enabling consumers to play an active role in their own health care. Today, this requires consumers to have a certain degree of health literacy within the context of e-health. To understand the extent to which existing studies have addressed health literacy within the context of Internet-based services, we conducted a systematic review of the literature. We performed four rounds of selection to identify relevant publications: database selection, keyword search, screening titles and abstracts, and screening the full text. This process produced a final sample of 42 publications. The findings from our review provide insights into how health literacy has been, and should be, addressed in the e-health era.
